I can assure you in all of my cases I have asked if anyone is going to show me my new car. Only one dealer (Mitsubishi) had someone that showed me the car and how to operate different things like the convertible top and how the cover went on, radio features, even went as far as popping the hood to show me where to fill the washer fluid, check the oil and so on.
On my 1993 Mustang back in the day the sales person attempted to show me, but had no clue what most things were like the red button in the trunk. It is the fuel shutoff switch. It pops when someone bumps you or you get in a wreck. Sometime even popped after going over Railroad tracks. Without knowing this you would pay for a tow truck believing that the car died and wouldn't start. All you have to do is press the switch back in.
On my 1993 Camaro they didn't have a clue because I bought the first one they got into the dealership.
On my Viper the dealership showed me nothing. It was a Toyota dealership and they knew nothing about the car. Not even how to pop the hood. I figured that out on my own to inspect the car. I got the car with no key fobs. I left and went to a nearby Wallgreens to get a phone charger and a drink before heading home (4 hr trip). I locked the doors. When I came back to the car I couldn't get into it. I had to call the salesperson to figure out how to get into the car with no keyfob.... This is how since there are no keyholes on the doors:
Use the key and pop the trunk. Alarm will sound. Reach in behind the drivers door and pull the manual door release. Then open the center console between the seats. At the top of it find the keyhole, put the key in it and turn to shut the alarm off.
So no, it's not about the new shiny car, it's about sales people not even knowing what they are selling. Even new car sales.
